SPINNING-RING.

SPECIFICATION forming part of Letters Patent No. 630,584, dated August 8, 1899.

Application filed March 8, 1899. Serial No. 708 218. (No model.)

To aZZ whom it may concern.-

Be it known that 1, JOHN BOOTH, of Gentral Falls, in the county of Providence and State of Rhode Island, have invented certain new and useful Improvements in Spinning- Rings, of which the following is a specification.

This invention relates to drop-forged and turned spinning-rings, such rings being made by first forking a steel blank and then turning the same on a lathe to the desired form. The ring-rails of ring-spinning machines are provided with holders formed to engage the base-flanges of the rings. Each holder is formed to fit a ring of a given size, and the rings as heretofore made are non-adjustable, each ring being capable of engagement with but one size of holder, so that if it is desirable to remove a set of rings and substitute therefor another set of a different size it has been necessary heretofore to provide a set of holders for the new set of rings.

My invention has for its object to provide an adjustable drop-forged and turned spinning-ring which while possessing the qualities of durability and. smoothness of finish found in rings of this character can be readily adapted to holders of different sizes.

The invention consists in the improvements which I will now proceed to describe and claim.

Of the accompanying drawings, forming a part of this specification, Figure 1 represents a sectional View of my improved spinningring, the form of the ring being that imparted by the operation of turning. Figs. 2 and 3 represent similar views, one showing the basefiange of the ring expanded and the other showing it contracted.

The same letters of reference indicate the same parts in all the figures.

In the drawings, 0. represents the travelerguiding portion, a the body portion, and a the base or holderengagingportion,ofaturned spinning-ring. The said ring is turned from in Fig. 1,) the blank being usually formed for the production of two rings. The form imparted by the turning operation is that shown in Fig. 1.

The traveler-guiding portion a is or may be of the usual form and projects from both sides of the body portion a. The base-flange or projects only from the outer side of the body portion and is therefore relatively narrow. The body and the flange a thus formed are capable of being expanded, as shown in Fig. 2, or contracted, as shown in Fig. 3, and thus adapted to holders of different sizes, either of these changes of form being readily imparted to the ring without interfering withits finish or otherwise injuring it. The narrow base enables the edges of the blank to be made correspondingly thin, as indicated by dotted lines in Fig. 1, so that the waste of metal in turning the ring is reduced to the minimum.

The ring shown in Fig. 1 may be considered as but partially completed. It is given its final form by either expanding or contracting its base-flange or by any well-known means or methods commonly practiced in any machine-shop or by any skilled workman. The method of expanding or contracting forms no part of my invention.

I claim- A turned spinning-ring having a relatively narrow base flange for engagement by a holder and projecting only from the outer surface of the body of the ring, whereby the said base-flange and body are adapted to be either expanded or contracted beyond or within the normal cylindrical diameter of the ring.

In testimony whereof I have aflixed my signature in presence of two witnesses.

JOHN BOOTH.
